Simple Steps to Prevent Common Cancers

Feb. 3, 2011 -- About a third of some of the most common forms of cancer could be prevented through healthy diet, physical fitness, and limiting alcohol intake, the American Institute for Cancer Research and the World Cancer Research Fund say in a new report.

About 7.6 million people die from cancer every year worldwide, and 12.7 million new cases are diagnosed. According to the Union for International Cancer Control, a third of cancer cases could be cured through early diagnosis and treatment and 30% to 40% could be prevented.

About 340,000 cases of cancer could be prevented annually in the U.S. if more people started eating a varied and healthy diet, started a regimen of physical activity, limited alcohol intake, and maintained a healthy weight, the new report says.

Exercise Reduces Cancer Risk

“Physical activity is recommended for people of all ages as a means to reduce risks for certain types of cancers and other non-communicable diseases,” says Tim Armstrong, MD, of the World Health Organization, says in a news release. “In order to improve their health and prevent several diseases, adults should do at least 150 minutes moderate physical activity throughout the week. This can be achieved by simply walking 30 minutes five times per week or by cycling to work daily.”

To reduce cancer risk, people also should quit smoking, avoid excessive sun exposure, and protect themselves against cancer-causing infections.
